public class E

extends Object

A class to handle debug message. It store messages until flush() is done, or autoflush() is called. It is useful for servlet enviroment. During the init() phase, one can not produce HTML output directly. So you can use E class in this way

	public void init(ServletConfig config)
		throws ServletException
	{
		super.init(config);     
      doYourInitWork();	
		E.debug("Initing done", 0);
	}
  

  // doGet Method - method that runs when the servlet is hit via GET
  

    public void doGet(HttpServletRequest req, HttpServletResponse res)
		throws ServletException, IOException
    {
		PrintWriter	out;
		res.setContentType("text/html");
		out = res.getWriter ();
		E.setOutput(out);    // set output channel
		E.flush();           // flush the acquired buffer, if any
		E.setAutoFlush(true);// now set autoflush
      doYourDoGetCode();
     }
 

E()

debug(String, int)

Print a debug message if its associated level is less then current DEBUG_LEVEL.

Note that:

• If autoflush is not true the message is buffered
• If autoflush is true but the PrintWriter channel is not setted via setOutput(), the message is discarded
